Previous happenings here: Ubuntu is booting into terminal instead of GUI Interface

For some reason when I boot my computer up, instead of automatically entering into my normal interface, I have to chose between my account and the guest account. When I try to log into my account, it tells me that my password is incorrect. It is NOT incorrect. I even changed it through the root menu and it still didn't work. So, I'm having to log in as a guest.

I have tried the command "sudo su" several times. And each time I do, it comes up with this: "sudo: unable to change to sudoers gid: Operation not permitted sudo: setresuid() [0, 0, 0] -> [124, -1, -1]: Operation not permitted"

I'm assuming it's because I'm in guest, but every time I try to type in a command, it tells me "permission denied" or something of that sort. I really need to log in to my regular account. It's not a password issue. In my recent post that I linked, I was told that it was probably either a malware issue (which I'm unsure of how to get rid of) or a security issue, as in, someone hacked into my computer. I'm not sure which it is. But I desperately need help. I have done nothing but research every response that I'm getting from the command-line, but everything that I've found hasn't helped because, like I said, every command I try to type just denies me permission.

If this is a malware issue, how do I fix it? If it is a security issue, how do I fix it? I'm not new to Ubuntu, but I've never had a problem like this before until I upgraded to 12.04. Please, any suggestions would be greatly appreciated!

Hi, Im afraid I am not sure what to do with your Normal account, but yes you are right, Guest account will not have the permission to SU. Also it is recommended to prefix the commands with sudo instead of using su. –  Karthik T Dec 26 '12 at 5:42
    
@KarthikT Thanks for letting me know. I just wish I knew of a way to log in, or why it's even messing up. –  Aubrey Dec 26 '12 at 17:10
